So in my spare time, I doodle aircraft drawings in mspaint. This is an imaginary 9 passenger utility autogyro with retractable gear which would fit in the same category as the Cessna Caravan and Pilatus PC-12. To me, it's a shame that autogyros always fell in the shadows of conventional airplanes and helicopters and are otherwise mostly restricted to hobbyist pilots in diminutive single or two seat designs. Hypothetically, I would market pic related as a light utility aircraft or business shuttle with extreme STOL performance (note the venturi air scoop on the rotor mast that provides cooling air for the electric pre-spin motor). The rotor can also be folded back for easy storage in a hangar. I've also been pondering a variant with floats but I'm not quite sure how that would pan out.

I figured I should share this with /n/ so that you guys could give it some decent livery (template in next post). In the meantime, we should have an autogyro appreciation thread while we're drawing.

It isn't particularly more efficient, it's just a different configuration.

>>
>>1152715
>>1152718
It is actualy less efficient than fixed wing.
The benefit of a autogyro is that it can land verticaly and start on a verry short runway.
>>1152785
Tiltrotors require some verry powerfull engines, but can not utilize them in horizontal flight due to the huge propellers.
Since the engines run at partial load most of the time, they run less efficient.

A zeppelin or a blimb does not suffer from these issues, could dock to skyscrapes and also does about 200 km/h depending on model.

Probably nothing. You can bring a can on a commercial flight now and nothing will happen, and the cabin pressure there is typically 8000 ft.

>bring a can on a commercial flight and nothing will happen
Security guard would caughy you out (if they are capable), I don't think there are any metal cola can that is smaller than 100ml and be transparent
>>1153220
I read that they won't, first they only ordered a hundred compated to thousand of Caravan they operate, second they're somewhat larger and more capable so simple 1 to 1 replacement would result in excess capacity

Explain

>>1154168
>Isn't plastic less plastic?
>>
>>1154393
>Explain
They require a high thrust to weight ratio, so they need much power and large propellers.
To utilize a engines full power during flight, you have to go fast.
If you go fast with large propellers, the tips of the blades reach the speed of sound and their efficiency drops drasticly.
Also they get verry loud.

Just look at the XF-84H "Thunderscreech", basicly a F-84F with a 4,365 kw turboprop instead of a jet-engine.

>>1151868
Purely Physics:

Firstly, the plane will start to spin in the opposite direction of the rotor spin because of Newton's third law, "for every reaction (the rotor spin) there will be a opposite and equal reaction (the plane will spin around the other way)". Now you must add a tail rotor on the end of the plane or add another rotor onto of the rotor spinning in the opposite direction to counteract the spinning force.

Secondly, consider how the rotor engine will fit inside this plane and the noise it will create.

Thirdly, the controls for a plane and a helicopter are completely different. In a helicopter, you have 3 things you need to control, one stick to control the angle of the rotor, one to control the pitch of the individual blades and the yaw pedals for directional control. While in a plane, you have a control stick and yaw pedals. How are you planning to combine the different controls on the plane?

Fourthly, the rotor will limit the top speed of the plane due to >>1152063 cus physics.
>>
>>1155377
Pretty simple layout. Main engine up forward, then your cockpit, then your main rotor engine and cowling, then your passenger cabin, storage, and tail rotor assembly.
>>
>>1155377
>the plane will start to spin in the opposite direction of the rotor spin
Pre-spinning the rotor takes place on the ground, the autogyro is at that point standing on its wheels, wich prevents itself from spinning.
>rotor engine
To spin up the rotor a small electric motor is sufficient, since you can do that with 0° pitch.
>controls for a plane and a helicopter are completely different
Not exactly, the controll inputs on stick and pedals are the same.
Roll and pitch (of the aircraft) are controlled via the stick and yaw via the pedals.
In the plane this is done by means of ailerons, elevator and rudder, in the helicopter by means of the swashplate and rear rotor.
Autogyros usualy use a swashplate and a rudder for that.
The only difference are pitch/flaps.
>>
>>1152137
I get why it didn't succeed with the airlines, but why not military? It seems like a much more sensible approach to VTOL than a shitrotor that's constantly trying to kill you.

OP, fyi that probably won't be faster than 180 knots so you should probably tweak that design for fixed landing gear. Would reduce unit cost a fair amount.
